Microsoft published a guide on how to install Linux.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I had a guide and it was still a big learning curve. Linus had a guide and he still bricked his machine trying to install Steam. Imagine your parents or grandparents being told without context to mount an ISO to a USB and set up their BIOS - for 90% of people there is no way in hell they're installing Linux without a guide unless they can double click an exe and have an install wizard do it for them.
I agree; but please take my comment in the context of Microsoft's guide - which doesn't tell users how to do any of things that you've mentioned. My point is that the underlying purpose of the guide is not so much about how to install linux, but how you might try linux while still keeping Windows.
